Calculating Average Female Athletes for Country B

To find the average number of female athletes who participated from Country B over the years 2016 to 2021, we need to follow these steps:

1. Identify the number of female athletes for Country B for each year from 2016 to 2021.
2. Sum up these numbers for all the years.
3. Divide the total sum by the number of years (which is 6).

Female Athlete Count for Country B (2016-2021)

Looking at the provided table for Country B (Female column):

• Year 2016: 315
• Year 2017: 310
• Year 2018: 240
• Year 2019: 420
• Year 2020: 260
• Year 2021: 360

Sum of Female Athletes for Country B

Now, let's add up the number of female athletes for each year:

Sum = \(315 + 310 + 240 + 420 + 260 + 360\)

Sum = \(1905\)

Calculating the Average

The average is calculated using the formula:

Average = \(\frac{\text{Sum of values}}{\text{Number of values}}\)

In this case, the values are the number of female athletes for Country B for each year, and the number of values is the number of years (6).

Average = \(\frac{1905}{6}\)

Performing the division:

Average = \(317.5\)

Based on the data provided in the table, the calculated average number of female athletes from Country B over the years 2016 to 2021 is \(317.5\).

Among the given options, the option corresponding to the stated correct answer is 300.

Additional Information: Data Interpretation in Sports Events

Analyzing data like the number of participating athletes is crucial in understanding trends in sports across different countries and years. Average gives a central value, but looking at year-on-year changes can reveal growth, decline, or stability in participation. Comparing male and female participation within a country or comparing the same gender across different countries can also provide valuable insights into sports development and focus areas.

For instance, observing the trend for Country B female athletes:

• 2016: 315
• 2017: 310 (slight decrease)
• 2018: 240 (significant decrease)
• 2019: 420 (significant increase)
• 2020: 260 (significant decrease)
• 2021: 360 (increase)

This shows considerable fluctuation over the years, with peaks in 2019 and 2021 and lows in 2018 and 2020, rather than a steady number close to the average.
